It is inevitable that the majority of computer users will come across new file
types on a fairly regular basis. Obviously, the more files you receive, the more
likely it is that this will happen.

It is important to
realize the risks before opening files that are delivered by email or that you
download from the Internet. While the majority of files may be safe to open and
use it would be naïve to believe that this will always be the case so some care
must be taken in these instances.

Care should always be taken when opening email extensions from unknown senders.
A good rule of thumb is to completely ignore them without a valid reason for
being sent that can be checked and verified before opening the file.

Unfortunately,
certain viruses or worms are spread using the contact email address book of
infected computers. This means that spurious looking emails with unwarranted
attachments even from people you do know should also be treated with extreme
caution.

The fact is that viruses and other malicious software and code can be spread
using a huge variety of file extensions. Vigilance should be concentrated more
on the sender of the email and the content of the email rather than the type of
file that has been delivered. Where it is possible to preview the file using
third party software this may provide a safer alternative to opening the file
properly and fully, although again some viruses can still be contracted in this
way.

Always ensure that you can view file types of attachments and other files before
opening them. Look for misleading file names as being a very good sign of
possible infection. For example, a virus may be named pictures.mpg but in actual
fact be a .exe file. By showing file extensions this would be displayed as
pictures.mpg.exe – this should immediately ring alarm bells and prevent you from
opening the file.

It may be possible
to repair the file extension associations in the Windows Registry.

RegCure offers you the ability to detect and
repair corrupt registry associations that may lead to file extensions not
opening or unknown file types that do not correctly identify the associated
program.
